The perimeter of the triangle formed by the points B(7,-9), C(7,-2) and D(0,0) is 25.68 square units.

Perimeter is defined as the distance or the enclosed path that surrounds the 2-D shapes or polygon. The perimeter of a triangle is the sum of all the three sides of a triangle.

The perimeter of a triangle formed by the points B(7,-9), C(7,-2) and D(0,0) can be determined by finding the distance between two points.

The distance between two points A(x1,y1) and B(x2,y2).

√[(x2-x1)²+(y2-y1)²]

Therefore, BC = √(7-7)²+(-2+9)²

BC = √49

BC = 7 square units.

and CD = √(0-7)²+(0+2)²

CD = √53

CD = 7.28 square units.

and DB = √(7-0)²+(-9-0)²

DB = √130

DB = 11.40 square units.

Therefore, perimeter of triangle formed from given points is BC+CD+DB =  7+7.28+11.40 = 25.68 square units.

Answer:Answer:

The measurement of the angle is 60

Step-by-step explanation:

The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore

Angle 5 + angle 6 = 180

If angle 5 is 120 degrees, then

Angle 6 = 180 - 120 = 60 degrees.

The vertical height of the rocket at the end of the third stage is 83.2 km.

We are provided that the rocket travels first 10 km vertically up (OA), then the rocket travels for 20 km (AC) at an angle of  15° from point A.

Let rocket travels 'a' distance vertically up(AB) during this,

then, rocket travels for travels for 60 km (CD) at an angle of  26° from point C.

Let rocket travels ' b' distance vertically up (BX) during this.

So,

Total Vertical Height Covered = 10 + a + b

So, According to diagram

In ΔABC

[tex]cos \ 15[/tex]° [tex]= \frac{a}{20}[/tex]

[tex]\\a = 20 * cos 15[/tex]° = 19.32km

In ΔCDE

[tex]cos \ 26[/tex]° [tex]= \frac{b}{60}[/tex]

[tex]\\b = 60 * cos 26[/tex]° = 53.9km

Since,

Total Distance = 10 + a +b

Total Distance = 10 + 19.32 + 53.9

Total Distance = 83.2 km

Therefore, Vertical height of the rocket at the end of third stage =  83.2 km

Step-by-step explanation:

as I said already in my answer to the duplicate post :

(4h⁴)⁴ = 4^1×4 × h^4×4 = 4⁴h¹⁶

for exponent of exponent we multiply.

n^-a = 1/(n^a)

There is no relationship between the number of movies and the number of sleep hours.

It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.

The scatter plot thus represented shows how one variable is related to another. In this case, we are trying to obtain how the number of sleep  hours tend to be related with the number of movies and this has been shown on the scatter plot that is shown in the question above.

It is clear from the statements in the question that the line of best fit would show that as the number of movies remained constant, the number of sleep hours decreased. This now implies that there is no relationship between the number of movies and the number of sleep hours.

the probability of drawing 2 red marbles from the bag will be 0.0455.

Number of Red marbles = 3

Number of blue marbles = 5

Number of green marbles = 4

Total marbles = 3 + 5 + 4 = 12

Probability of drawing 2 red marbles from the bag will be:

P = 3 / 12 × 2 / 11

P = 6 / 132

P = 3 / 66

P = 1 / 22

P = 0.0455

Therefore, the probability of drawing 2 red marbles from the bag will be 0.0455.

Answer: It is m<U = 60 and m<V = 120 (x = 20)

Step-by-step explanation:

1. We know that these 2 angles are supplementary, which means both adds up to 180 degrees.

2. So first, we do this:
             3x + 2(m<U) = 180
          2a. We do this to find m<U

3. We can also notice that 3x is m<U, so substituting m<U with 3x makes sense. 3x + 2(3x) = 180

4. We then simplify:
3x + 6x = 180
9x = 180

5. We will then divide:
x = 20

6. With the new found info, we substitute x with 20:
m<U = 3(20)
m<V = 2(3(20))

7. Doing the math, it becomes:
m<U = 60
m<V = 120

Using it's concept, the probability of at least 1 red face upper most is 17/18 = 0.9444 = 94.44%.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For each cube, the probability of no red faces is:

Hence the probability of no red faces in anu cube is:

1/6 x 1/2 x 2/3 = 1/18.

Which means that the probability of at least 1 red face is given by:
